Regarding the switching threshold for NIR-SWIR AC

[maxi_arena]

Hi,
Following switching threshold proposed by Liu et al (2019) https://doi.org/10.1016/j.isprsjprs.2019.04.013.
I’m trying to apply the switching scheme using the Rrs(645) > 0.009 sr−1 instead of the Turbidity index. I’m wondering if there’s any possibility to set it directly in the L2gen or should I process the NIR and SWIR AC and then, mersh the outputs without using Seadas?.

No, you cannot pass a parameter to l2gen to modify the Shi and Wang NIR/SWIR switching algorithm to use an Rrs_645 threshold in place of the turbidity index.

If you process both SWIR and NIR in separate runs you can use SeaDAS' Math Band operator to blend the output.
